SIGNALING.

EPECIFICATION forming part of Letters Patent N 0. 716,301, datedDecember 16, 1902.

Application filed January 29, 1902. Serial No. 91,812- (No model.)

To all whom it may concern.-

Be it known that LRAYMOND C.SPAULDING, a citizen of the United States,and a resident of Montclair, in the county of Essex and State of NewJersey, have invented certain new and useful Improvements in Signaling,of which the following is a specification.

Myinvention relates generally to signaling, and more specifically to asystem in which a sound-producing device and a light-producing deviceare controlled by a common operating means.

The object of my invention is to appeal to more than one sense whensignaling and in this way to render it more certain that the signal hasbeen noticed and apprehended by the person or persons for whom it isintended. Its use will be readily understood in its application to anautomobile, for example, as morefully described hereinafter, where theintermittent sounding of the horn will be accompanied by a flash oflight for each blast. This flash may be produced simultaneously with thesounding of the horn, or a steady light may be extinguished momentarilyevery time the horn is sounded and relighted after each blast. For thispurpose a separate light from the headlight or the latter itself may beused, according to circumstances.

In the drawings I have embodied my invention in several forms; butchanges and modi-.

fica-tions may of course be made within the scope of the claims.

In the said drawings, Figure l is a general View of the elementsembraced in the system appliedto the horn of an automobile embodying myinvention. Fig. 2 is a detail View, partly in section, of the bulb andadjacent elements shown in Fig. 1. Figs. 3 and atshow modifications ofthe system shown in Figs. 1 and 2. Fig. 5 shows a detail of Figs. 3 and4. Fig. 6 shows an adaptation of my invention in connection with asteam-whistle.

Similar letters of reference indicate corresponding parts in thedifferent views.

A represents a bulb which when compressed sounds the horn 'B in theusual manner by vibrating the diaphragm b, interposed in the passage W.This passage 12 is provided with a tube 0, located between the bulb andthe diaphragm, so as to divert part of the air to act upon the plunger0', the lower end a of which forms a movable electrode adapted tocontact with the stationary electrode c when it is moved into its closedposition by the pressure of the air. The lower end of the tube 0 andadjacent elements may be inclosed in the box X.

The movable and stationary electrodes are both connected by means of theline-Wires d and (Z properly insulated, with the light (1 the latter ofthe two wires being connected with the battery D. It will now be readilyunderstood that when the bulb A is compressed the air will produce theusual sound in vibrating the diaphragm and will also move the plunger 0down so that its lower end a will come in contact with the stationaryelectrode 0 thereby closing ,the circuit and producing a flash of thelight at (1 The plunger is returned to its normal position by the actionof the spring 0 when the air-pressure ceases. This operation will berepeated every time the bulb is compressed, the horn being sounded andthe flash of light produced simultaneously.

WVhen it is desired not to produce a flash of light, as in the day-time,the valve 0 is simply turned, thus preventing the passage of air throughthe tube C. In case it is desired to have the light d steady it is onlynecessary to close the shunt-switch d thereby producing the desiredresult.

In Fig. 3 and 4 the reverse order is observed, the light being normallysteady and intermittentlyextinguished whenever the movable electrode isbrought out of contact with the stationary electrode by the action ofthe air. This is accomplished in this instance by making the tube 0communicate with the closed compartment E, provided at its lower endwith the stationary electrode 0 and having its movable electrode 0attached to a flexible diaphragm e adapted to be inflated by thepressure of the air. The two electrodes are properly, insulated, and thepassage of the movable electrode back to its normal position isfacilitated by means of the spring a in contact at all times with themovable electrode 0 the line-wire passing through the insulation 6 ofthe box E to the said spring, thereby maintaining constant communicationbetween the battery and said electrode.

In Fig. 6 is shown an adaptation in connection with a steam-whistle F,the steam passing through the pipe f, having the Valvef interposed,being diverted through the small pipe f to the reducing-valve f thenceto the movable electrode contained in the box f operating in the samemanner as in the case of the construction shown in Figs. 1 and 2.

It is of course obvious that changes may be made within scope of theclaims and that I do not limit myself to the exact construction shownherein.

Having thus described my invention, what i I claim is 1. In signaling,the combination of a soundproducing device, actuated by fluid-pressure,an electric circuit, a light-producing device located in said circuit, aswitch controlling the circuit and light-producing device, means forproducing fluid-pressure to operate the sound-producing device, andmeans whereby the said pressure operates the controllingswitchsimultaneously therewith.

2. In signaling, the combination of a son ndproducing device, actuatedby ii uid-pressu re, an electric circuit, a light-producing devicelocated in said circuit, a switch controlling the circuit andlight-producing device, means for producing fluid-pressure to operatethe sound-producing device and means whereby the said pressure closesthe controlling-switch simultaneously therewith.

3. In signaling, the combination of a soundproducing device, actuated byfluid-pressure, an electric circuit, a light-producing device located insaid circuit, a switch controlling the circuit and light-producingdevice, means for producing fluid-pressure to operate thesound-producing device, means whereby the said pressure operates thecontrolling-switch simultaneously therewith and means for operating thesound-producing device and the light-producing device independently ofeach other.

4. In signaling, the combination of a soundproducing device, actuated byfluid-pressure, an electric circuit, a light-producing device located insaid circuit, a switch controlling the circuit and light-producingdevice, means for producing fluid-pressure to operate thesound-producing device, means whereby the said pressure closes thecontrolling-switch simultaneously therewith and means for operating thesound-producing device and the light-producing device independently ofeach other.

5. In signaling, the combination of a horn, an electric circuit, alight-producing device located in said circuit, a fluid-operated switchcontrolling the circuit and light-producing device, a compressible bulb,for creating fluidpressure to sound the horn, communicating with thelatter, and means for diverting part of the fluid-pressure to operatethe switch simultaneously with the sounding of the horn.

6. In signaling, the combination of a horn, an electric circuit, alight-producing device located in said circuit, a fluid-operated switchcontrolling the circuit and light-producing device, acompressible bulb,for creating fluidpressure to sound the horn, communicating with thelatter, and means for diverting part of the fluid-pressure to close theswitch simultaneously with the sounding of the horn.
